Potato glycoalkaloids(PGAs) are potentially toxic to humans at high levels and current safety regulations have recommended that PGAs content in tubers of potato cultivars should not exceed 20 mg/100g·FW. Accordingly, it is important to determine the PGAs composition and levels on potato cultivars for food safty and the breeding for new cultivars with low levels of PGAs. The main aim of this study was to evaluate α-chaconine, α-solanine and total PGAs content in the peel and cortex portions in 24 cultivars including ‘Haryoung’, ‘Goun’, ‘Hongyoung’ and ‘Jayoung’, recently released by Highland Agricultural Research Institute. The total PGAs ranged from 3.1 to 10.1 mg/100g·FW. 75-94% of total PGAs was existed in the peel part of all cultivars. We selected two cultivars, which can be eaten wth the skin on tubers, and so used for soy sauce braised potatoes and baby potatoes for the rest area. These results will provide consumers and breeders with fundamental information about the content of PGAs in Korea major cultivars.
